Let X and Y be independent exponential random variables with pa- rameter ? = 1. Given that X and Y are independent, their joint pdf is given by the product of the individual pdfs of X and Y , that is, fX,Y(x, y) = fX(x) fY(y). The joint pdf is defined over the same set of x-values and y-values that the individual pdfs were defined for. Using this information, calculate P (X ? Y ? 2) where you can assume...
